Find all instances of "Missing Script"
Is there a method to list all instances of a 'Missing Script' after moving/deleting a file,
My experiment with junction and a common library of scripts seems to have failed, and left me with quite a mess to clean up!
Even though it's a question from a long time ago, a while ago I made a plugin for this, "$$anonymous$$issing Script Hero": http://forum.unity3d.com/threads/released-missingscripthero-finding-missing-script-references-the-easy-way.273925/
This is pretty insane I'm sorry to say. Imagine you have a huge scene and half your nodes have "missing scripts"..I mean comeone ! You might as well throw your game out the window.
I have made a tool to find out all missing references.

Is there a way to deter$$anonymous$$e the name of a missing script and replace it automatically (using an editor script)?
AFAI$$anonymous$$, that possibiliy got optimized away with 3.5. With <3.5, the referenced file would still be listed as a string in the binary asset (scene, material, prefab, ...) (which often helped us a lot if somebody deleted an asset at some point from the Asset Server, and you wanted to figure out which "$$anonymous$$issing Script" was originally referenced.
But since 3.5, they switched entirely to GUIDs, so assets are no longer referenced by path/name. There is AssetDatabase.GUIDToAssetPath(), but IIRC it returns null if the asset is no longer in the database. :-(
@Wolfram Would you $$anonymous$$d demonstrating how to achieve this using GUIDs? I am not sure if you'll get this follow up comment. I certainly didn't get an e-mail notification of your comment...
2021, wiki site can't be reached. Used the wayback machine to pull it up:

I wrote a post + code examples for how to find missing references and missing components:
http://www.tallior.com/fixing-missing-references/
It's very useful, we're using it whenever we hit these cases.
Not sure if I'm following. If you know the name of the script but don't know which objects use it, you can create a script with that name and the following contents:
function Start () { print("Script XYZ used by " + name); }
Not it was more to find objects that have orphaned "$$anonymous$$issing Script" entries.. IE: you have a bunch of objects that use script XYZ.cs, but then you delete that script file, but there are still entries on the objects that need to be 're-connected'
EX: Rena$$anonymous$$g a file outside of the unity project window can break things.
also cases where trying to Junction a set of standard scripts across multiple projects will cause the disconnection
I just read in another post (search "Mass Set Materials") where the scriptor used:
Undo.RegisterSceneUndo("Mass Set Materials");
This apparently allows you to Undo effect of your script.
Now, regarding you're earlier problem, I too have had that problem, and don't have a solution. I do think using this Undo method might help your experiments though. It is placed in the Start(), I recall.
Hope you find your answer - it will help a lot of us, I'm sure.
This is an old problem. I would start with the Component Copier in the Asset Store (a real bargain!), and see how it uses Reflection. The idea would be to look at what fields are on a script to try to match them up with existing scripts and see what fits best. But I don't think you can get at those fields once the script has gone missing (even though they still show up in the Inspector UI. Those are in the library/cache and we don't have (official anyway) API's to get at that. But then, you might look into the meta files and see what might be useful there.http://unity3d.com/support/documentation/Manual/ExternalVersionControlSystemSupport.html
Nothing, just the GUID of that particular asset. But if a script got deleted, the .meta file gets deleted along with it, and there is no way to recover the original path from a merely referenced GUID.
Yeah just checked that myself, was gonna delete that suggestion from my post. I had started working on an 'asset vault' system that would catalog scripts for just such occasions as I was tired of running into this problem. Ins$$anonymous$$d I got into the habit of exporting my scenes as packages and archiving them.
That vault sounds like a good idea.
I seem to remember we got inconsistencies when transfering assets from project A to B via packages in 3.5, since the GUIDs of identical assets were different between projects...(might be their file locations were different, so they got different GUIDs, but so far I didn't investigate this further).
